Drake has claimed his rap rival Kendrick Lamar performed the diss track Not Like Us at the Super Bowl Halftime Show to "assassinate (his) character" in front of million of viewers.
The Hotline Bling rapper sued the record label Universal Music Group (UMG) for defamation in January over Lamar's track Not Like Us, in which he is accused of being a paedophile.
In an amended complaint on Wednesday, Drake focused on events that have taken place since the initial filing, including Lamar's Super Bowl headline performance and his Song and Record of the Year wins at the Grammys in February.
His lawyers claimed that Lamar further promoted the single and damaged Drake's reputation by performing Not Like Us for millions of people who had never heard it before, or the diss tracks that preceded it, at the Super Bowl.
"It was the first, and will hopefully be the last, Super Bowl halftime show orchestrated to assassinate the character of another artist," they wrote in the complaint, reports Variety.
His legal team noted that the Alright rapper didn't say the word "paedophile" during his performance because "nearly everyone understands that it is defamatory to falsely brand someone a 'certified pedophile'."
In relation to the Grammys, the attorneys urged that UMG executives consented to Not Like Us being played during the broadcast, despite their ongoing lawsuit with Drake. Both musicians are signed to record labels owned by UMG.
The rapper's lead attorney, Michael Gottlieb, told Variety, "Drake's amended complaint makes an already strong case stronger. UMG's PR 'spin' and failed efforts to avoid discovery cannot suppress the facts and the truth. With discovery now moving forward, Drake will expose the evidence of UMG's misconduct, and UMG will be held accountable for the consequences of its ill-conceived decisions."
In a lengthy response, UMG representatives blasted the "frivolous and reckless lawsuit", which they described as "an affront to all artists and creative expression".
"We will demonstrate that all remaining claims are without merit," they continued. "It is shameful that these foolish and frivolous legal theatrics continue. They are reputationally and financially costly to Drake and have no chance of success."
Last month, UMG lawyers filed a motion to dismiss the lawsuit, claiming that Drake only took legal action because he "lost a rap battle".
A hearing about the dismissal petition is set for 30 June.
